Product Description

PRODUCT FEATURES

High detection accuracy, simple

operation method, no damage to

the sample to be tested; The sample

surface can be scanned for defects;

Physical properties such as

thickness, conductivity and

permeability of conductor samples

such as conductor film and metal

sheet were tested.
PRODUCT INTRODUCTION

LSNT-300 nondestructive testing system: It can detect the thickness, conductivity, permeability and other related

physical characteristics of conductor samples such as conductor film and metal plate under test without direct

contact with the sample to be tested. At the same time, it can scan the surface of the sample for defects. It can be

widely used to test the thickness, conductivity, permeability and other physical characteristics of conductor samples

such as conductor films and metal plates.

Image analysis description

Surface defect measurements were made for grooves of aluminum plate samples with different

depths (i.e., defects), as shown below. The defects from left to right are: (a) surface grooves with

a depth of 1mm; (b) Surface grooves with a depth of 3mm; (c) is an internal groove with a

thickness of 4mm from the surface; (d) is an internal groove with a thickness of 1mm from the

surface; (e) is a through-hole slot; The width of each hole and slot is 10mm. Aluminum has an

electrical conductivity of 3.78X10 7 (S.m-1 ) and a permeability of 1.2566X10 -6 (H.m-1 ).

LabVIEW program was used to control the automatic scanning system to scan the surface of the

sample in accordance with the red snake path set in the figure, and set the Z-axis step distance

of 1.25mm each time (you can set the specific value according to the situation), the scanning

area of 70×118mm, the total number of calculated measuring points is 56×94 5264 points. In

order to consider the influence of skin effect and better obtain the surface topography of the

sample, the detection conditions at different frequencies of 200, 500, 1500 and 5000Hz were

tested respectively. The defect location was determined by high frequency first, and then the

specific size and depth of the defect was further obtained by adjusting to low frequency. Finally,

the surface and near-surface morphologies of the samples were obtained.
